Illustration of the evolved SLS Block 1B Crew variant night launch. This configuration of the rocket, with the Exploration Upper Stage, will provide in-space propulsion to send astronauts in NASA’s Orion spacecraft and heavy cargo on a precise trajectory to the Moon. The evolution of the rocket to SLS Block 1B configuration with EUS enables SLS to launch 40% more cargo to the Moon along with the crew. Manufacturing both the core stage and Exploration Upper Stage is a collaborative effort between NASA and Boeing, the lead contractor for EUS and the SLS core stage. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission. The SLS rocket, NASA’s Orion spacecraft, Gateway, and human landing system are part of NASA’s backbone for deep space exploration. Under the Artemis program, NASA is working to land the first woman and the next man on the Moon to pave the way for sustainable exploration at the Moon and future missions to Mars.

These images show NASA employees attending an event April 10, 2025, at Marshall Space Flight Center in Huntsville, Alabama, to view the Orion stage adapter for Artemis II before it is transported to NASA’s Kennedy Space Center in Florida. Manufactured entirely at NASA Marshall, the adapter plays a crucial role in connecting the SLS (Space Launch System) rocket’s interim cryogenic propulsion stage to the Orion spacecraft. This adapter is the final piece of SLS hardware to be delivered to Kennedy Space Center in preparation for the Artemis II mission.

NASA finished assembling and joining the main structural components for the largest rocket stage the agency has built since the Saturn V that sent Apollo astronauts to the Moon. Engineers at the agency’s Michoud Assembly Facility in New Orleans connected the last of the five sections of the Space Launch System (SLS) rocket core stage Sept. 19. The stage will produce 2 million pounds of thrust to send Artemis I, the first flight SLS and NASA’s Orion spacecraft to the Moon. The engine section is located at the bottom of the 212-foot-tall stage and houses the four RS-25 engines. The core stage’s two liquid propellant tanks and four RS-25 engines will produce more than 2 million pounds of thrust to send the SLS rocket and Orion on the Artemis lunar missions. The engine section houses the four RS-25 engines and includes vital systems for mounting, controlling and delivering fuel form the propellant tanks to the rocket’s engines. Offering more payload mass, volume capability and energy to speed missions through space, the SLS rocket, along with NASA’s Gateway in lunar orbit and Orion, is part of NASA’s backbone for deep space exploration and the Artemis lunar program. No other rocket is capable of carrying astronauts in Orion around the Moon in a single mission.
